NOTE: Ongas models,routineservicingcanusu-

ally be accomplished within the limited movement provided by the gas hose restraint. If the oven needs to be moved further from the wall, the gas must first be turned off and disconnected from theoven before removing the restraint. Reconnect the restraint after the oven has been returned to its regular position.

It is essential that an adequate air supply to the oven be maintained to provide a sufficient flow of combustion and ventilation air.

Place the oven in an area that is free of drafts.

Keeptheovenareafreea nd clearof allcombustiblessuchaspaper,cardboard,andflammable liquids and solvents.

Do not place the ovenon a curb baseor seal to awall.Thiswill restricttheflow of air and prevent proper ventilation to the blower motors. This condition must be corrected to prevent permanent damage to the oven.

VENTILATION

Ongasmodelsthenecessityforaproperlydesigned and installed ventilationsystem cannotbe over emphasized. This s ystem allows the oven to function properly while removing unwanted vaporsand productsof combustionfrom theoperating area.

This oven must be vented with a properly designed mechanically driven exhaust hood. The hood should be sized to completely cover the equipment plus an overhang ofat least 6” (15cm) on all sides not adjacent to a wall. The distance from the floor to the lower edgeof thehood should not exceed 7’ (2.1m). The capacity of the hood should be sized appropriately and provisions should be made for adequate makeup air.

GAS PIPING

Aproperlysized gassupply systemis essentialfor maximum oven performance. Piping should be sized to provide a supplyof gassufficient to meet themaximumdemand ofall applianceson the line without loss of pressure at the equipment.

Example:

NOTE: BTU values in the following example are

for natural gas.

You purchase a MT3240G conveyor oven to add to your existing cook line.

1. Addthe BTUratingofyourcurrentappliances. Pitco Fryer 120,000 BTU

6 Burner Range 60,000 BTU Deck Oven 50,000 BTU Total 230,000 BTU

2. Add the BTU rating of the new oven to the total.

Previous Total 230,000 BTU MT3240G 100,000 BTU New Total 330,000 BTU

3. Measure the distance from the gas meter to the cook line. This is the pipelength. Let’s say thepipelengthis30’(9.14m)andthepipe size is 1” (2.54 cm).

4. Usethe appropriatetable todetermine the total capacity of your current gas piping.

The total capacity for this example is 375,000 BTU. Since the total required gas pressure, 330,000 BTU is less than 375,000 BTU, the current gas piping will not have to be increased.

NOTE: TheBTU capacitiesgiven in the tables are

for straight pipe lengths only. Any elbows orother fittings willdecreasepipecapacities. Contactyour local gas supplier if you have any questions.

PRESSURE REGULATION AND TESTING

MT3240G ovens are rated at 100,000 BTU/Hr. (24 kW/Hr.) Eachoven hasbeen adjusted at the factory to operate with the type of gas specified on the rating plate a ttached to the left side of the control panel.

Each oven issupplied with a regulator tomaintain thepropergaspressure.The regulator isessen-

tial to the proper operation of the oven and shouldnotberemoved.Itis preset to providethe

oven with 3.5” W.C. (0.87 kPa) for natural gas and

10.0” W.C. (2.50 kPa)for Propanewhile the flame is on. The regulator is located on top of the gas valve, between the manual shutoff and solenoid valves.

DO NOT INSTALL AN ADDITIONAL REGULATOR WHERE THE OVEN CONNECTS TO THE GAS SUPPLY UNLESS THE SUPPLY EXCEEDS THE MAXIMUM.

NOTE: The maximum gas supplypressure to the

oven is 10.5” W.C. (2.61 kPa) for natural gas and 13” W.C. (3.2 kPa) for Propane gas.The minimum gassupply pressure to the oven is 4.5” W.C. (1.1 kPa) for natural gasand 11.0”W.C.(2.74kPa) for Propane gas.

Installation must conform with local codes, or in the absence of localcodes, with the National Fuel

Gas Code, NFPA54/ANSI Z223.1---Latest Edition, the Natural Gas Installation Code CAN/CGAB149.1 or the Propane Installation Code, CAN/ CGA-B149.2 as applicable.

The oven and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressuresinexcessof1/2psig(3.45kPa).

The oven must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas piping system at test pressures equal or less than 1/2 psig (3.45kPa).

Installation

Gas Connection

GAS HOSE RESTRAINT

If the oven is mounted on casters, a commercial flexible connector with a minimum of3/4” (1.9 cm) inside diameter must be used along with a quick connect device.

The restraint, supplied with the oven, must be used to limit the movement of the unit s o that no strain is placed upon the flexible connector. The restraint should be fastened to the base frame of the oven as close to the flexibleconnector as possible. It should be short enough to prevent any strain on the connector. With the restraint fully stretched the connector should be easy to install and quick connect.

Therestraint (ie:heavygauge cable)shouldbe attached without damaging the building. DO NOT use the gas piping or electrical conduit for the attachment of the permanent end of the restraint! Use a nchor bolts in concrete or cement block. On wooden walls, drive hi test wood lag screws into the studs of the wall.

WARNING!! If the restraint is disconnected for any

reason it must be reconnected when the oven is returned to its original position.

U.S. and Canadian installations

The connector mustcomply with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors For Moveable Gas Appliances CAN/CGA-6.16 and a quick disconnect device that complies with the Standard for QuickDisconnect Devices for Use With Gas Fuel, ANSI Z21.41or Quick Disconnect For UseWithGasFuel CAN 1-6.9. Adequate means must be provided to

limit the movement of the appliance without depending on theconnection and the quick disconnect device or its associated piping.

A drip leg must be used at each appliance. Refer to NFPA54/ANSI Z223.1 - Latest Edition (National Fuel Gas Code) for proper drip leg installation.

General export installations

The restraint and quick connect must conform withLocal and Nationalinstallationstandards. Local installation codes and/or requirements may vary.Ifyouhaveanyquestionsregardingtheproper installation and/or operation of your Blodgett oven, please contact your local distributor.
